In Peroxide We Trust: A Cost-Effective Approach to Soil Microplastic Extraction

Soil is and always has been a defining aspect of human society and a key provider of insight into the nutrition and health of Homo sapiens. Soil Fertility is the ability of soil to facilitate plant growth by providing favorable physical, chemical, and biological nutrients & minerals (CHNOPS). Microplastics are toxic materials, less than or equal to 5 mm in length, which invade the world’s soils through urban sewage, amalgamating themselves with the SOM, thus threatening all biodiversity on Earth. Soil Sample Coordinates within 4-inch precision: 34°04'36.4"N 84°18'01.9"W. The Hydrogen Peroxide experimental group had a mean pH value of 6.09 for the entirety of the 40 days, which was significantly different than the pH of Birch seeds (6.44) and Control (6.51) groups. Future research can use NPK concentrations of a soil sample for testing soil fertility in addition to pH alone. Researchers in upcoming studies could also experimentally determine the efficiency of Hydrogen Peroxide as a density separation method for soil microplastics at different experimental variables, such as soil type, microplastic type, and temperature ranges, which could yield completely different results.
